Ask Dr. Z

Is a cooled radiofrequency neurotomy of three genicular nerves reported with unlisted code 64999, or can I use the new RFA code 64624 for this procedure? "Fluoroscopy was used to identify appropriate entry sites for radiofrequency genicular neurotomy of the superolateral, inferomedial, and the superomedial nerves. Once radiofrequency introducers position was confirmed, motor and sensory stimulation testing was completed. Each nerve was tested first with a radiofrequency probe in place; motor testing was complete @ 2Hx with a range of .1V to 2.5V. Sensory testing @ 50 Hz with maximum of 1.5V was then completed. The radiofrequency probes were placed into the superolateral, inferomedial, and the superomedial nerves, and treatment was initiated at each site with 90 seconds of radiofrequency lesioning completed at 85 C degrees. After lesioning, 40 mg Depo-Medrol was injected through the introducers at each site."
